Printing Machine Bearings
-- Steady & Reliable Manufacturer --
Brief Description
Ultra-high precision (P4/P2) bearings designed for printing cylinders and rollers, ensuring absolute minimum runout and low vibration for consistent, flawless high-speed image transfer.
Introduction
The quality of modern printing, especially offset and gravure, depends entirely on the rotational accuracy of the cylinders. This requires bearings of the highest precision class, often P4 (ABEC 7) or better, to maintain the extremely tight gap (the "kiss") between rollers. Our printing machine bearings are manufactured under strict conditions to ensure minimal radial and axial runout. Furthermore, they feature specialized sealing and shielding to protect against ink mist, paper dust, and cleaning chemicals, guaranteeing the extended operational life required by high-volume commercial printing.
